K&F Concept 49mm Circular Polarizer Lens Filter Ultra-Slim Optical Glass

Great polarizer for landscape photography! I have not been disappointed in any of my K&F Concept filters. The terrain really pops and creates the right amount of definition in color. I have stacked this with other filters and love the combos.

Vary good CPL with carrying case. Does what you expect it to do. No color cast. Smooth adjustability of the polarization to remove glare from where you don't want it. Helps to keep the sky from blowing out and stop reflections.

Amazing value for the money made with quality feeling metal and works great. While it doesn’t 100% get rid of some glare for the price it works amazingly creating a night and day difference. For the value, you can’t get any better. Sadly, the lens cap does not like staying on with this filter on but that isn’t a dealbreaker when you have a cheap lens filter, that will protect your lens

Honestly, the best $20 I have spent on my camera. This camera does magic on automotive photography; making glass clear, removing reflections, and possibility increasing vibrancy without any drawbacks. One issue I have is that it is SUPER hard to get off the lens (or a step up adapter in my case). I wasn’t able to get it off until I used a rubber jar opener to twist it. I didn’t even tighten the filter much. Overall, can’t wait to use it more, dreading taking it off again. Would recommend K&F for filters overall, maybe not the ultra-slim.

Works great, good quality and price for the money

Buen material

I realy want to know horizontal or vertical the small tactile grooves on the CPL give you an idea

I’m not using a fixed focus point and shoot or disposable camera. I’m using a full frame mirrorless camera. I bought this K&F CPL to improve image colours and reduce reflections. Instead ithis CPL destroys images by severely reducing sharpness and focus. Anything with any detail is weirdly blurred away. The best images I kept are soft as if I used a diffusion filter. The only reason I kept photos taken with this CPL is they weren’t local. Don’t waste your money. I shot over 300 pics the past few days and only about 20% taken with this CPL filter were kept. The rest of my keepers were taken without any filter. I confirmed my complaint by a simple test. I put my camera on a tripod to lock on a subject. I took test pics using no filter, a Hoya CPL, and this K&F CPL. My subject was clearly in focus with the Hoya CPL and no filter. With this K&F CPL, the same exact areas on the same subject showed softness and smudged details. The difference was immediately noticeable. Sadly this ruins my confidence in anything from K&F. Unfortunately 80% of my day trip photos taken with this K&F circular polariser were trashed by simply using this junk. I’m so disappointed I don’t even feel like wasting my time and money by exchanging this filter for another. DON’T bother. DON’T be tempted and fooled.

works well

A pretty good CPL filter. I like the quality, but there is one downside - lens cap no longer fits :(

Dobry produkt
